Given that the Prosine allows you to set lower and upper voltage limits for transfer to inverter, isn't this doing exactly what an autoformer does? Or even a surge protector?
I realize that instead of transforming the current it kicks over to battery, but this can have the effect of protecting equipment from bad power, right?
First a surge protector does not protect against low voltage, or even high voltage, it protects against surges and spikes. A power line monitor/controller protects against over/under volatage.. Many people insist on calling them Surge Protectors but that is only part of their function.
However here is how a a good power protection system works
if the voltage goes too high, or low, AND STAYS THERE, it cuts off. If it's a passing surge or spike it clips and/or limits it... but if the surge (or dip) goes on too long they cut you off CLICK and it's dark
Now, the Prosine, also monitors but if it sees the voltage go out of range (or frequency, which some power-guard systems can also monitor) or waveform, it switches to INVERTER mode, and continues to provide power..... Till the batteries run down.
Not at all the same thing.
Now an auto-former is yet another beast. There are two brands that are popular and that I know about, plus a few more that I don't know
The HUGHES monitors for LOW voltage, and if it sees low voltage it BOOSTS the voltage to make up for the brown out.. It does not monitor frequency, it does hoave some spike supression in it.
The FRANKS also does that. plus it monitors for OVER voltage (Not common in the US, common in Mexico) and can BUCK the voltage if it's too high.
Another difference is the prosine is only 2,000 or 3,000 watts. The Autoformers can deliver up to 120000 watts (50 amp) or 3600 (30 amp) as can the power guard devices.
